MotorSim 2 is a sophisticated performance calculator tailored for land vehicles, designed to offer enthusiasts and professionals a detailed analysis of vehicle dynamics. Please note that this application is not a driving game but serves as a tool for physical simulation, focusing specifically on the performance of vehicles during straight-line acceleration.

With MotorSim 2, users have the ability to customize various technical attributes of a vehicle and observe the impact on its performance. The app features an interactive simulator that includes a speedometer, RPM meter, throttle, brake, and gear shift mechanisms, which can be set to either manual or automatic. It also generates engine sounds procedurally, rather than through sampling, and visualizes the vehicle's position on a 1/4 mile track segment. Users can save a 'ghost' or 'shadow' of a configuration's performance, allowing for later comparisons with other settings.

The configurable parameters in MotorSim 2 include:

• Max Power
• Power curve, which can be defined point by point
• Torque curve, automatically defined by the power curve since power equals torque multiplied by RPM
• Max engine RPM, where ignition cutoff occurs
• Gears configuration, with up to 10 gears available
• Resistances, such as Cx (drag coefficient), frontal area, and rolling resistance coefficients
• Vehicle weight
• Tyre size
• Shift time
• Transmission efficiency

The performance metrics calculated by MotorSim 2 include:

• Maximum speed
• Acceleration from 0-60 mph, 0-100 mph, 0-200 mph, 0-300 mph, and beyond
• Any additional performance metrics that can be measured using the interactive simulator

MotorSim 2 is an invaluable tool for anyone looking to delve deep into the mechanics and potential of land vehicle performance, providing a comprehensive platform for simulation and analysis.
